In over 85-90% of cases one single laser treatment is sufficient. In others, a second laser treatment is necessary to help you achieve the optimum vision. At BoydVision your laser vision correction is covered for retreatment up till 18 months after surgery. After that there is a fee for any further follow up visit, but you are eligible for retreatment at a reduced fee ($395/eye) indefinitely, as long as it is medically safe to do so. Blended Laser treatments are separate than regular Custom Laser Vision correction, and have a separate fee charge.
